Let go of grudges
Forgiving and forgetting is necessary for your own happiness, as holding a grudge means you're also holding onto resentment, anger, hurt and other negative emotions that are standing in the way of your own happiness. Letting go of a grudge frees you from negativity and allows more space for positive emotions to fill in.
Go ahead and dream big, as you'll be more likely to accomplish your goals. Rather than limiting yourself, when you dream big you're opening your mind to a more optimistic, positive state where you have the power to achieve virtually anything you desire.
Don't sweat the small stuff
If the issue you're mad about will be irrelevant a year, a month, a week or even a day from now, why sweat it? Happy people know how to let life's daily irritations roll off their back.
Speak well of others
It may be tempting to gather around the office water cooler to get and give the daily gossip, but talking negatively about others is like taking a bath in negative emotions; your body soaks them up. Instead, make it a point to only say positive, nice words about other people, and you'll help foster more positive thinking in your own life as well.
Live in the present
Allow yourself to be immersed in whatever it is you're doing right now, and take time to really be in the present moment. Avoid replaying past negative events in your head or worrying about the future; just savor what's going on in your life now.
Don't compare yourself to others. Your life is unique, so don't measure your own worth by comparing yourself to those around you. Even regarding yourself as better than your peers is detrimental to your happiness, as you're fostering judgmental feelings and an unhealthy sense of superiority. Measure your own success based on your progress alone, not that of others.
Nurture social relationships
Positive social relationships are a key to happiness, so be sure you make time to visit with friends, family and your significant other.
What you eat directly impacts your mood and energy levels in both the short and long term. Whereas eating right can prime your body and brain to be in a focused, happy state, eating processed junk foods will leave you sluggish and prone to chronic disease. My free nutrition plan is an excellent tool to help you choose the best foods for both physical and emotional wellness.
Exercise boosts levels of health-promoting brain chemicals like serotonin, dopamine, and norepinephrine, which may help buffer some of the effects of stress and also relieve some symptoms of depression. Rather than viewing exercise as a medical tool to lose weight, prevent disease, and live longer – all benefits that occur in the future – try viewing exercise as a daily tool to immediately enhance your frame of mind, reduce stress and feel happier.
Clutter has a way of sucking the energy right out of you and replacing it with feelings of chaos. Clutter is an often-unrecognized source of stress that prompts feelings of anxiety, frustration, distraction and even guilt, so give your home and office a clutter makeover, purging it of the excess papers, files, knick knacks and other "stuff" that not only takes up space in your physical environment, but also in your mind.
Accept what cannot be changed
Everything in your life is not going to be perfect, and that's perfectly all right. Happy people learn to accept injustices and setbacks in their life that they cannot change, and instead put their energy on changing what they can control for the better.
